They kinda created this fake locked down market that people expect to be able to be used, same as Apple, compared to say, just downloading apps normally like on a computer.

Also "sideloaded" apps cannot be automatically updated, although personally I think it would be better if nothing could automatically update lol

I'm also not the biggest fan of Steam. But at least on Steam if I search for Brotato it's the top result, Steam is not tied to the OS so if gamers and game makers decided they hate Steam they could jump to some other market (as opposed to, say, the built-in Microsoft store in Windows that thankfully seems to be failing), and Steam has helped drag Linux into the 21st century in a good way.
